Claims that acetaminophen (Tylenol) during pregnancy causes autism or ADHD have spread online, but major medical groups dispute them as unsupported. The real guidance: treat pain and fever appropriately with the lowest effective dose for the shortest time, under medical advice.
Take: Don't let viral clips scare you off needed medicine. Untreated fever is riskier; ask your OB before use and avoid extra or long-term dosing.
